Rose plant Korampa of the Floribunda class

ABSTRACT

A floribunda rose variety having a pale orange bud and flower, stiff and heavy textured petals, large foliage, resistance to rose powdery mildew, few thorns, straight stems, and slight fragrance.

This present invention relates to a new and distinct variety of roseplant of the floribunda class which was originated by me by crossing thevariety ANABELL with an unnamed variety.

The primary objective of this breeding was to produce a new rose varietysuitable for use as a cut flower in a pastel to ivory shade. Thisobjective was substantially achieved along with other desirableimprovements as evidenced by the following unique combination ofcharacteristics which are outstanding in the new variety and whichdistinguish it from its parents, as well as from all other varieties ofwhich I am aware:

1. Bud and flower color of a pale orange tint, equivalent to R.H.S.group 20, C and B.

2. Stiff, heavy textured petals, opening slowly to a well imbricatedopen flower.

3. Large foliage, resistant to rose powdery mildew.

4. Few, straight thorns.

5. Straight, rigid stems.

6. Slight fragrance.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated.
